BUTTON.

SPECIFICATION forming part of Letters Patent No. 555,995, dated March 10, 1896. Application filed March 9,1893. Serial No. 465,227. (NO el- To aZZ whom it may concern: Y

Be it known that I,.JAMES W. BEAUMONT, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Buttons, of which the following is a specification.

My improvement applies to that class of buttons which are constructed in two parts, adapted to be attached to a garment at any required point by thrusting the pointed shank of one part through the garment and engaging it reliably with the other part applied on the other side of the garment.

In my improved button the shank is formed on a fastener which is applied from the wrong side (the inside) of the garment, and it engages with the main body which is presented on the right side (the outside) of the garment bybein g forced in and partially turned therein. This general mode of fastening has been long known and approved. My invention makes it more secure. I produce a slotted opening in the hub of the back or collet and produce on the shank of the fastener a correrespondingly-flattened end, which is triangular, the point adapted to pierce the fabric and divide it by separating the yarns, preferably without cutting them, and the back or shoulders square. This is inserted through the garment from the back, and the bodyof the button is applied thereon with its slotted aperture in the position to receive it. After the parts have been compressed together and partially rotated relatively to each other these square shoulders bear fairly against the inner face of the collet and prevent the removal of the button.

In the interior of the button-bodyI mount a slightly-bent spring of thin hard metal eX- tending across and engaged at each end with the periphery of the button, so that it cannot be rotated. This spring presents its slot transverse to the slot in the collet.

To set the button, the shank is inserted through the material from the back, and the button-body is applied with its slot in the position to receive the flattened portion of the shank. The latter cannot thus enter the slot in the spring; but on the parts being compressed together with sufficient force the spring yields and allows the shank to be indirection, and consequently the button remains reliably fastened.

The accompanying drawingsform a part of this specification and represent What I consider the best means of carrying out the in vention.

Figure 1 is a side View of the entire button engaged in the garment. Fig. 2 is a view of the rear face of the body alone. Fig. is a plan view of the collet with the cap removed, showing the spring in place. Fig. 4 is a central cross-section through the button and fastener, taken on the line at 4 in Fig. 3. Fig. 5 is a corresponding view at right angles to Fig. 4:. It is taken on the line 5 5 in Fig.3. Fig. 6 is a front view of the fastener alone. Fig. 7 is a face View of the spring detached.

Similar letters of reference indicate corresponding parts in all the figures where they appear.

A is the front or cap of the body overlapping and engaged with the collet in the long approved manner. The collet B is formed with a hub of the ordinary character, except that its center is provided with awinged hole Z) Z). The main portion of this hole I) is circular and of a size oorrespondin g to the cylindrical portion of the shank D. The wings I) Z) are small open slots adapted to allow the reception of the flattened portion D of the shank when it is properly presented. The periphery of the collet is notched at two opposite points, as indicated by b 11 C is a spring of hard brass or other suitable material extending across the'interior of the body of the button and engaged byits properly-formed ends with the notches b If. In

the center of this spring is a slot 0 of proper size to receive the flattened portion D of the shank.

In applying the parts together the shank strikes the spring with its flattened portion D standing transverse to the slot 0. In this position it cannot enter such slot, and on the parts being sufficiently compressed together the spring 0 is deflected toward the front plate or cap A until the whole of the flattened portion D of the shank is received within the button-body. Then, on turning the latter a quarter around, or holding the button-body stationary and turning the shank around by its head D to a corresponding extent, or by turning each part a little, so that the two shall be revolved to the proper extent relatively to each other, the flattened part of the shank is brought to coincide with the slot 0 in the spring. This spring receives it and instantly resumes its original form, taking a reliable hold of the flattened portion D of the shank to prevent its being turned in either direction. Thereafter the button cannot be disengaged.

Modifications may be made without departing from the principle or sacrificing the advantages of the invention.

Instead of making the spring 0 a narrow strip of metal extending across the button it may be wider. I have shown the slot 0 as of V-shaped section, or having the metal immediately adjacent deflected, adapted to facilitate the entrance of the pointed shank, but it may be a plain slot. It is important to give the spring a just sufficient amount of elastic yielding. It must be sufficiently yielding to be deflected by the thrusting force received through the shank in attaching the parts and yet sufficiently stiff when it has assumed its original position to hold the parts efficiently locked. The spring 0 may be sufficiently held against turning by engaging with only one notch, 12 or b I prefer the whole as shown.

I claim as my invention- 1. In a two-part button a spring 0 in the interior of the main body having a slot 0 extending longitudinally of said spring, in combination with a collet or back forming a fixed portion of the button having a hole 6 in its center and win-gs or notches Z) 19 forming open slots on opposite sides of said hole in a line crossing the line of the said slot 0, adapted to serve with a fastener having a flattened part and capable of being turned partially within the body substantially as herein specified.

2. In a two-part button, a body comprising a collet, having a slotted aperture 19, b, and a peripheral notch N, in combination with a spring 0 within the body engaged in such notch, and having a slot 0 arranged transversely to the said aperture in the collet and with a fastener having a shank D, flattened part D and head D all arranged to serve substantially as herein specified.

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.
